Abstract
A current or voltage sensor for use with a busbar has a support body having a proximal end juxtaposed with the busbar and a distal end spaced therefrom and a U-shaped conducting bar in the proximal end and having a pair of arms having free ends transversely engaging the busbar. A Rogowski coil in the proximal end is juxtaposed with the U-shaped conducting bar. A grounded screening element at the distal end is conductive and forms a chamber open toward the U-shape conducting bar. A source electrode has a proximal end engaging the U-shaped conducting bar outside the first chamber and a distal end in the chamber. An electrical field sensor in the first chamber is juxtaposed with the distal end of the source electrode.
